VOLU-probe/1SS for Round Ducts Installation Procedure

INSPECTION & HANDLING. VOLU-probes should be carefully inspected for damage prior to installation. Report damage to

your Freight Department, or contact delivery carrier. Almost any means of handling can be utilized depending on the length and

weight of the probes. Probes may be handled while in any position, however, it is important not to drop or mishandle the probes

such that damage is done to the sensing holes, tubular members, signal connection fittings, end studs, or mounting plates.

ORIENTATION OF PROBES. Using the AIRFLOW directional arrow on the probe mounting flange to determine correctorientation, install VOLU-probes with sensing holes facing airflow.

INSTALLING VOLU-probes. To achieve published performance standards, the location of VOLU-probes in ductwork

must comply with the Minimum Requirements for Installation submittal sheet (Page 7).

VOLU-probe must be mounted so that the sensing holes on the probes are at the centers of equal areas in the duct. If three

probes are furnished (as illustrated below), the angle between each probe is 60. If two probes are furnished, the angle

between probes in 90. The radial dimension (R) between probes is determined by the formula R=C/2N where C is the

duct circumference and N the number of probes. VOLU-probe insertion holes (F) and end support holes (G) must be cut in

the duct on center lines.

FASTENERS. Gasket mounting surfaces should be clean and burr free. VOLU-probe mounting plates are predrilled for

" mounting fasteners. Air Monitor recommends the use of-18 bolts, nuts, and lock washers (or flat washers and

lock nuts). Fasten-ers should be stainless steel to be compatible with probes.

DIMENSIONAL SPECIFICATIONS.

VOLU-probe/1SS

THREAD SEALANT.

Appropriate thread sealant should be selected depending on maximum air temperature. use of a high temperature pipe

sealant at the probe signal fittings is recommended Teflon tape or equivalent products are not recommended for high

temperature applications

SIGNAL TUBING. Signal tubing commences at the total and static pressure takeoff connections at the center of the

interconnecting tubing array shown in Details B and C. Two signal tubing conditions are possible; tubing with an AUTO-

purge panel and tubing without an AUTO-purge or CAMS panel.

If an AUTO-purge panel or CAMS panel is not furnished, signal tubing for total and static pressure take-off connections

may be 1/4" O.D. if the distance from the measuring device to the transmitter is 200' or less.

If an AUTO-purge panel is furnished, the total and static pressure signal tubing should be sized per the following Table:

It is not recommended that AUTO-purge panels be located more than 50 feet from takeoff connections. Signal tubing

from the purge panel to a transmitter should be sized 1/4" if the distance is 200' or less.

CAUTION:After tubing is completed, signal lines should be leak tested prior to operation. Care must be taken not to

overpressurize measuring device.

AIRBORNE CONTAMINANTS .

The levels of air filtration and cleanliness associated with commercial HVAC Systems, whether supply/return/exhaust/

outside air, are satisfactory for operation of the VOLU-probe. Industrial applications containing airborne contaminants

may require periodic manual or automatic cleaning using compressed air applied to the signal fittings, and/or removal from

the duct or stack for physical cleaning.

MINIMUM REQUIREMENTS FOR INSTALLATION.

Note: VOLU-probe locations shown are NOT ideal. They indicate the minimum clearance required from air turbulence

producing sources. Wherever possible, the VOLU-probe should be installed where greater runs of straight duct (or

clearances) than shown exist.
